Vincent Pastore, a k a Big Pussy of “The Sopranos,” threw a party for his play “Wild Children,” loosely based on his life in the 1980s running the Crazy Horse Cafe in New Rochelle. Although a work of fiction, the play is full of his memories of the time. Pastore threw the bash Thursday at his current bar, the Montauk Lounge in New Rochelle, and we’re told it even included an appearance by Stephen Baldwin. The sold-out play ran at the Nyack Village Theater until April 28.
